Letters Patent No. 78,739, dated Jima 9, 1868.

IMPROVEMENT 'IN '.PROPFLLRSI` To ALL WHOM IT MAY eoNoERN:

Be it known that I, D. H. HEYEN, of New York, in the county and State of New York, have-invented anewand improved Canal-Boat Propeller; and I do hereby declare that the following is a full, clear, and exact vdescription thereof, which will enable others skilled in the art to make and use the same, reference being had tothe accompanying drawings forming part of this specification.

VThis invention has for its object the construction and arrangement 0t` a propeller-wheel, which shall he adapted to thepropulsion of boats on canals, more especially, but which may be used to propel boats on all navigable waters; and also in the construction of the boat itself, whereby it is suited and adapted tothe use of the wheel,` as will be hereinafter' more fully described.

i Figure 1 is a sectional side elevation ofthe skeleton of the boat with the wheel attached, the section being through ma of tig. 2.

Figure 2 is atop or plan viewfrom the line y y of tig. 1. Similar letters of reference indicate corresponding parts. A is the keel of the boat. l i IB represents -the ribs.

C is the propeller-wheel, which is placed on the end of-a horizontal shaft at the bow-end of the boat. D is the-propeller-shaft. I Thepropeller-wheel is made adjustable by an arrangement which allows the shaft to be moved laterally on n. 'central pivot or ball-journahpwhich ball is confined in the journal-box oi' the shaft, as seen in the drawing at E.

The back or innr end of the propeller-shaft is confined in a journal-box on a movable plate, which plate is marked F.

This plate is supported by a block of' suitable height, which rests on the bottom vof the boat or otherwise, in-a iixed position, which blck is .marked G. In the block 'a bolt, e, isconfined, and d isa slot in the plate F. The head ofthe bolt laps `over on to,thc plate from the slot, so that the plate is coniined totheblock, while it is allowed to move longitudinally, carryf ing the end of the shaft, and thereby altering the position ofthe wheel. The outer edge of this plate is a cogged rack, as seen in the drawing.

h is a pinion on the end of'the upright shaft J, which engages with the rack. The shaft J is partially rotated by the hand-wheel'K when it is desired to alter the position of the wheel. The ribs of the boat are made ot' iron, and the form of the bow'of the boat is varied fromthe ordinary eh'ape,'in` order. to accommodate the wheel, as seen in the drawing. 4 v

The keel of the boat is extended forward at the bow, so as to support the forward or ball-journal box of the shaft.

In navigating canals by steam, especially when there is a side wind, or when turning short curves in the canal, or when lit is necessary to move' the lbow of the-boat laterally without headway, this device for altering the position of the wheel is ot' great importance-as thereby the bow of the boat may be moved laterally with. perfect ease, either with or without headway,.and the iniiuencc? of a side wind is-readily counteracted.

The Vrudder of the boat may be operatedwith chains or ropes, if desired, soA that one man may manage the wheel, and attend to the rudder also.

at is the shaft-journal on the. plateF. v i O is the engine-shaft, from which the propeller-shaft is driven by a band er by gearing, 11s-may be most convenient.

I is a-pulley on theengine-shat`t,and R is a pulley on the propeller-shaft, -for using arbeit. The propellernvheel may have two'or more blades, set at any desired angle. i 4 Having thus described my invention, what I claim as new, and desire to-secure by Letter Patent, is l. The combination of the. propeller-wheel C and shaft D, when adjustable laterally upon the central pivot E, slotted segmental plate F, support-G, pinion'h, upon 'the upright shaft J, e'ngine-shft O, pulley P, and pulley R, all arranged as described for the purpose specified.

2. The combination of the-propeller C, shaft D, having the ball-joint E, slotted segmentiF, and pinion 71,. upon the shaft J', all constructed and operating as and for tlie purpose specified.

The above Specification of my invention signed by me, this 21st day of December, 1867.

' D. H. HEYEN.
